For many years, there has been a demand for aluminum sheet and plate alloys that could deliver several notable advantages for high-strength welded applications compared with alloys such as 5052 and 6061. Fabricators have been looking for improved design efficiency, enhanced welding performance, good forming ability, excellent corrosion resistance, and cost-effectiveness similar to other non-heat-treatable alloys. Metallurgical advancements have led to the development of alloys 5083 and 5086, which provide superior weldability and meet these requirements. The two alloys share nearly identical characteristics, although 5083 offers slightly higher mechanical strength due to its increased manganese content compared to 5086.
GNEE supplies these alloys for applications such as unfired pressure vessels, missile containers, heavy-duty truck and trailer structures, boat hulls, and marine superstructures.
What are the properties of 5086 H32 aluminum?
At 20 °C (68 °F), H32 strain hardened 5086 has a yield strength of 195 MPa (28.3 ksi), an ultimate tensile strength of 208 MPa (30.1 ksi), and 6-12% elongation.
What is the difference between 5083 H32 and H321?
Both 5083-H32 and 5083-H321 aluminum are variations on the same material. They have the same alloy composition and many physical features, but their mechanical properties change due to processing.
The 5086 H32 aluminum alloy is well recognized for its excellent corrosion resistance, strong mechanical properties, and good machinability. The H32 temper denotes a medium-strength state, giving the alloy sufficient durability and the ability to withstand harsh environmental conditions. These characteristics make 5086 H32 a suitable choice for maritime, shipbuilding, outdoor structural applications, and various industrial uses. Additionally, it is compatible with anodizing, which enhances both its appearance and corrosion resistance, making it ideal for long-term outdoor performance.
In terms of weldability, the 5086 H32 aluminum alloy is highly weldable. Its medium hardness allows for easier welding and ensures strong and reliable weld joints. Proper heat control and welding techniques, however, remain important for achieving optimal weld quality. When it comes to bending, 5086 H32 is easy to form due to its moderate hardness, offering flexibility in shaping processes and expanding its usefulness across multiple applications.
The corrosion resistance of 5086 H32 is exceptional, particularly in seawater, atmospheric exposure, and other aggressive environments. This makes it especially suitable for marine and outdoor structural applications. The alloy also performs well in high-vibration conditions, making it valuable in automotive, aerospace, and defense industries. Its high durability and long service life further enhance its reliability in demanding environments.
The advantages of 5086 H32 aluminum alloy include high corrosion resistance, good weldability, excellent bendability, and suitability for vibration-intensive applications. However, its medium hardness may limit its use in applications requiring higher strength, and it may not machine as easily as softer alloys. Despite these limitations, 5086 H32 remains an excellent choice for outdoor and industrial projects that require durability and consistent performance.
